TRUCK, WHEEL, AND ARMATURE EXCHANGE FOR STREET OR OTHER RAILWAY CARS.

SPECIFICATION forming part of Letters Patent No. 656,133, dated August 14, 1900. Application filed November 23, 1899. Serial No. 738,100. (No man.)

To all whom it may concern.-

Be it known that 1, WILLIAM H. CORNNER, a citizen of the United States, and a resident of Anderson, in the county of Madison and State of Indiana, have invented certain new and useful Improvements in Truck, Wheel, and Armature Exchanges for Street or other Railways; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the ac companying drawings, and to letters and figures of reference marked thereon, whichiform a part of this specification.

the invention. Fig. 2 is a section on the line m m, Fig. 1. Fig. 3 is a cross-section on the line y y, Fig. 1. Fig. 4 is a longitudinal section, partly broken away, of a modification of the invention as in application. Fig. 5 is a detail View of the bar I and support L.

This invention has relation to means for facilitating repairs in electric or other traction vehicles, and is designed to provide means whereby the trucks of such vehicles may be readily exchanged or broken wheels or other parts readily removed and replaced; also, whereby the motors can be removed or exchanged as may be necessary, all in a manner to prevent strain or injury to the car and its running-gear. Heretofore repairs and exchanges of this kind have usually been made by first jacking up one end of the car, with the other end remaining on the track,to a sufficient height to permit the desired parts to be removed and replaced. This operation is not only laborious in character, but causes great strain on the car, which often results in breakage. The present invention is designed to obviate operations of this character and to provide simple and convenient means whereby the trucks or any part thereof, as well as the motors, may be readily removed and replaced without the necessity for jacking or raisingsthe car-body. I

The invention consists in the novel con struction and combination of parts, all as hereinafter described, and pointed out in the appended claims.

Referring to the accompanying drawings, the letter A designates the floor of a carshed or repair-shop, B tracks laid upon the same, and C a pit sunk below the level of the floor and over which the tracks B run.

D designates tracks which run through the pit some distance above its bottom.

E designates a suitable framework for supporting the tracks B and D. Said tracks B are provided with the vertically-movable seo tions 1 and 2 of sufficient length each to support a car, and the portions E of the frame E, upon which said movable sections are supported, are arranged to rise and fall in the pit upon the guides G at each side. The lower tracks D have portions thereof removed underneath the sections 1 and 2, so that the said Figure 1 of the drawings is a plan view of sections when lowered will come to a level therewith and complete their continuity. Said sections E are supported upon jacks H in the bottom of the pit, by means of which they may be raised and lowered.

G indicates transverse bars extending the full width of the track and working in slots G2 of the supporting-framework. These bars are arranged to be moved under the end portions of both rails of each movable section 1 and 2 to support the same in raised position and to be moved from under said sections'to allow the same to be lowered.

The two sections 1 and 2 are separated from each other by a fixed section 3. Underneath each of the sections 1 and 2 is provided a central transverse bar I, having its ends movable in or upon guides J of vertical posts E of said framework. Each of said bars has a motorsupport L, pivoted thereto to swing in a horizontal plane, and each bar has a vertical movement in the guides J independent of the movement of the frame-sections bymeans of a j aok M or other suitable mechanism.

The operation is as follows: The car to be repaired is run onto one of the sections 1 or 2, and its body is blocked or propped up. Its trucks are then unfastened, and the section 1 or 2, with the truck thereon, is lowered until the upper tracks B are level with the lower tracks D. The trucks can then be run out on the lower tracks to the end of the pit,where repairs and replacements can be readily made. It is then run back under the car, raised to place, and reattached to the car, or the old truck may be run out-of the way entirely and a new one supplied.

For changing the motors or their armatures the car is stopped on one of the movable sections over the bar I, which is utilized to lower the 01d motor or armature and raise a new one to place. The support L being pivoted as above described can be swung to position to facilitate placing or removing a motor or its armature therefrom.

By means of the second movable track-section old parts may be raised from the pit and carried ofl? and new parts lowered into the pit. I may, however, use only a single vertically-movable track-section.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-=- 1. Means for facilitating car-repairs, comprising a pit having an interrupted track therein, a track extending over said pit and having a section vertically movable in guides over the interrupted portion of said firstnamed track, transverse bars extending the full width of said track, working in slots of supporting-framework for said track, and arranged to be moved in under and support the end portions of both rails of said verticallyinovable track-section, and to be moved from under the same to allow said section to be lowered, together with supplementary verti cal guides, and a transverse armature-supporting bar working in said guides, and having a central pivoted motor or armature rest, substantially as specified.

2. Means for facilitating car-repairs, comprising a pit, a car-track extending over said pit and having a section movable into and out of said pit, a motor or armature supporting carriage also in said pit and vertically movable therein, said carriage having a pivoted motor or armature rest, substantially as specified.

In testimony whereof I alfix my signature in presence of two Witnesses.

WILLIAM II. CORNNER.
